Description

A kind of nano combined fertilizer is in the method that promotes the Lettuce volume increase

Technical field

What the present invention relates to is the implantation methods of a Plants, relates in particular to a kind of implantation methods of Lettuce.

Background technology

Lettuce, have another name called the naked oats dish, the some places dish (do not know " common sowthistle flower is opened " whether this winter in winter) of grieving again, belong to the chrysanthemum material, is to take the sharp blade profile leaf that the tender tip, tender leaf be product to use the nest lettuce, blade is long lanceolar, that color and luster is talked is green, quality is tender and crisp, and mouthfeel is very fresh and tender, delicate fragrance, have peculiar flavour, contains the nutrient components such as a large amount of vitamin and a large amount of calcium, iron, protein, fat, vitamin A, vitamin B1, vitamin B2, be to eat top grade in vegetables raw, the title of " phoenix tail " is arranged.Efficient cultivation method about Lettuce does not have ripe method.

Summary of the invention

The present invention is directed to the deficiencies in the prior art provides the efficient cultivation method of the Lettuce that a kind of survival rate is high plus nano composite fertilizer to be added on wherein.

The present invention realizes above-mentioned purpose by the following method.

A kind of nano combined fertilizer, in the method that promotes the Lettuce volume increase, is characterized in that the method comprises the following steps:

(1) slotting machine configuration and management,

(2) seed treatment,

(3) sowing processing,

(4) final-period management,

(5) transplant and transplant rear management;

It is characterized in that: described (5) are managed and are adopted nano combined fertilizer after transplanting and transplanting, raw material by following each weight percentages of components forms: urea 15-19%, MAP 2-4%, potassium sulphate 4-6%, potassium dihydrogen phosphate 4-7%, the nanoclay 10-20% that the granule diameter is 10-20nm, humic acid 10-15%, BA3-5%, water 5-10%, shitosan 1-5%, borax 3-7%, zinc chloride 0.5-1%, sodium molybdate 0.05-0.3%, manganese sulphate 0.05-0.1%, neopelex 0.05-0.3%, ferrous sulfate 0.8-2%, magnesium sulfate 0.03-0.8%, copper sulphate 0.01-0.05%, dimethyl sulfoxide (DMSO) 0.2-2%, field crop stalk 2-10%, fowl and animal excrement 2-3%,

Described fowl and animal excrement is a kind of or any several mixing in pig manure, cow dung, sheep excrement, chicken and duck excrement;

This composite fertilizer is prepared as follows:

(a) choose the raw material of formula ratio by described parts by weight;

(b) by described field crop crushed stalk, be powder;

(c) described fowl and animal excrement, field crop stalk powder are mixed, mix thoroughly, the wet feed of banking up in fermentation vat fermentation, on cover the moisture-heat preservation material, after 60 hours, turning for the first time when in heap, temperature reaches 50-70 ℃, and every turning in 24 hours once, after 3 turnings, fermentation ends;

(d) by tunning and described urea, MAP, potassium sulphate, potassium dihydrogen phosphate, the nanometer ferrous sulfate, nano-sized carbon, humic acid, lignin, BA, water, shitosan, borax, zinc chloride, sodium molybdate, manganese sulphate, neopelex, ferrous sulfate, magnesium sulfate, copper sulphate, dimethyl sulfoxide (DMSO) mixes puts into reactor, and water dissolves, and is uniformly mixed reaction 2 hours under 100-120 ℃; After technique to be mixed completes, with 200 mesh sieve filtering solutions, remove residue.

Add by weight percentage described nanoclay in filtering solution, stir and obtain final products.

Described nanoclay preparation method is: by attapulgite, imvite mixed solution at 0 ℃ of lower stir-activating 4 h, add lauryl sodium sulfate, 5 * 104 r/min high shear 5 h, reaction solution is cooled to decompress filter after room temperature, gained is deposited under 105 ℃ and is dried to constant weight, obtains nanoclay.

The configuration of described (1) slotting machine and management: selection matrix is that humus soil+turfy soil+vermiculite mixes by weight 3: 2: 1 ratios, bordeaux mixture with 0.1%, 0.1% carbendazim, 0.1% chlorophos is sprayed on the matrix stirred, carry out sterilization processing, being made into length on greenhouse or open country is that the 4.5-5.0m width is 1.5-2.3m, the slotting machine that thickness is 0.35-0.40m, insert front 2 d, disinfecting solution of potassium permanganate with 1.5 ‰, till dosage reaches slotting machine bottom and has liquid to flow out, 1d before sowing, start sprayer unit, the slotting machine of drenching, to reduce the acid of matrix, basicity and salt ionic concentration, and with carbendazim 0. 2% liquid sterilization again,

Described (2) seed treatment: seed is soaked 2.5 hours in nutrient solution, and the described nutrient solution of taking root consists of:

BA 0.6-0.9g/L

NAA 5.0-7.5g/L

KT 3.2-3.8g/L;

(3) sowing is processed: the seed after step (2) is processed disseminates on bed, the 2cm that sowing depth is cutting length, and line-spacing is 6cm, and spacing in the rows is 3cm, after planting with 1.5 ‰ liquor potassic permanganate, sprays immediately, and every square metre is sprayed 2.5L;

(4) final-period management: put up shading shed above seedbed, light transmittance 50%, the high 1.5m of canopy, observe three indoor temperatures, humidity every day, and the suitable humidity of seedling development is 80%, preference temperature is 23 ℃, at this moment the door that can suitably open booth is ventilated, and at 5 o'clock in afternoon, while being down to below 20 ℃, closed the doors and windows in time, to keep normal temperature, after cuttage, in January, spray water at any time; Insert and sprayed 1 time 3 ‰ potassium dihydrogen phosphates after latter 15 days to every 6 days of the last ten-days period in September, fertilising stops carrying out after spraying between the lights; Because canopy temperature is high, high humidity, germ reproduction is fast, and Resistance of Seedling is poor, easily infects, and control is crucial, after inserting, can spray Rogor, and tpn is prevented and treated disease, and 7 days one spray medicines, be used alternatingly;

(5) transplant and transplant rear management: the seedling that transplanting time 12-22 in October day survives the cuttage sowing is transplanted to preprepared nursery lot, selects physical features smooth, and draining is good, and nursery lot is set up in the deep rich soil of soil layer; Transplanting method is transplanted the front sunken bed of nursery lot being done to growth 5m, wide 2.5 m, uses sufficient base fertilizer, then cuttage seeding is transplanted by 15cm * 25 cm seeding row spacings, and transplanting depth 2.5 cm, water permeable in time after transplanting;

Transplanted seedling is managed vegetative period every described nano combined fertile 100 dilute solutions of 15 d foliage-spray, and after the transplantation of seedlings of land for growing field crops, the transplant survival rate reaches more than 96%.

Described nutrient solution consists of:

IAA 1g/L

NAA 6.0g/L

KT 3.5g/L

ABT-6 0.2 g/L。

The Lettuce that the method obtains possesses following advantage with respect to prior art:

1, the application provides a whole set of Lettuce implantation methods,, system more complete with respect to prior art, and final survival rate has reached more than 95%;

2, strictly control various conditions, comprise sterilization to matrix and slotting machine, to the control of temperature, humidity, and be mixed with applicable nutrient solution, this series of preparation is conducive to the root base and is differentiated to form adventive root, improves survival rate;

3, the matrix of medium of seedling bed special ratios, compound fertilizer are conducive to insulation water suction, permeable, ventilation, and germ is few, take root fast.

Through time for many years, greatly shortened the time of breeding by method of the present invention, and, through a series of preparation, made the survival rate of nursery stock to reach more than 95%.
